Varistor maybe? T4094008

Hi @DigiKey_Internal -
Hope this finds everyone safe and sound.
I have a photo here of what I am thinking is a Epcos/TDK Varistor (maybe one of these) but I’m not sure how to make out which one it could be.

Anyone know what the K20 or 9811 marking is in relation to?

You might be correct, could be TDK.

Pretty sure it’s this one:

B72207S0200K101

Note one of other names is “S07K20”.

9811 almost certainly indicates it was manufactured the 11th week of 1998.
